IMPROVEMENT IN THE MANUFACTURE OF WEATHER-BOARDING.

Specification forming part of Letters Patent No. 132,318, dated October 15, 1872.

weather-boarding, as will be hereinafter morefully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construct-ion and operation, referring to the annexed drawing, in which- Figure l is a perspective view, showing my weather-boarding applied; and Fig. 2 is aperspective view of the mode of constructing the planks or boards for my weather-boarding.

In the construction of my weather-boardin g I use planks or boards dressed on both sides, and of double the thickness required. In one edge of the plank or board is cut a V-shaped groove, a, and the plank or board is then split in two, as indicated in Fig. 2, thus forming two boards, A A, ready for weath er-boarding. The groove to forms a bevel along one edge on the inner side of each board A. This bevel is made according to the width and thickness of the planks or boards used, in about the following proportion: On a board half an inch thick and six inches wide, the beveled edge should be one-eighth of an inch thick, and the bevel run toward the center of the board one and one-half inch. These bevels, or in other words the groove a, may be made by the simple means of a beveled circular saw on either side, running over and forward of the saw that splits the plank or board; or, the groove may be cut by a side head on the planing-machine, similar to the grooving head on a flooring-mill. The beveled side of the board always goes against the studding B, as shown in Fig. 1, making a perfect joint where the boards lap and a firm seat for the nail to be driven into, thus preventing the boards splitting by driving the nails. It also makes a much stronger building than the usual weather-boardin g, without any increase in the cost.

Having thus fully described my invention,

what Iclaim as new, and desire to secure by Letters Patent, is

The within-described weather-boarding, formed by makiii g a V-shaped groove in one edge of a plank or groove dressed on both sides and splitting the same, thus leaving a 'a bevel along the edge on the under side of each board, substantially as and for the pur- LEMUEL POSTLEWAIT.
